1224 REVISION OF THE GENUS HETERONYX, 



without more definite indication of locality ; its labrum is said to 

 rise to the level of the clypeus, but nevertheless the clypeus to be 

 scarcely even sinuous in front ; it appears to be a small species 

 (long. 3-3J lines), of a brownish-testaceous colour, with close fine 

 puncturation, bidentate front tibiae and strongly bifid claws. 



GROUP II. 



In the tabulation of the species (Proc. L.S.N.S.W. 1888, pp. 

 1329-31) I find a slight ambiguity of expression; — certain species 

 being divided as having "E— the hind coxae considerably (EE 

 scarcely, if at all) shorter than the metasternura on the external 

 margin." H. solidus (under the former initial) is separated from 

 H. JBeltance and satelles as having the hind coxse '' very little " 

 shorter than the metasternum. The difference here indicated very 

 satisfactorily separates the species, and the " very little " of solidus 

 is quite distinct from the " scarcely, if at all " of mqualis and 

 holosericeics, — but as it is undoubtedly obscurely worded in my 

 tabulation I suggest the substitution (p. 1330, lines 26-30) of the 

 following, — 



L. Hind angles of pro thorax (viewed 

 from above) appear well-defined 

 [size more than 4 lines] solidus, Blackb. 



LL. Hind angles of prothorax (from all 

 points of view) appear quite 

 rounded oflf [size less than 4 

 lines] 



Neither am I quite satisfied with my treatment in this group 

 of the claw structure which (since the issue of Part I. of the 

 " Revision") I have found to be more useful for distinction of species 

 than I at first thought. I think it well therefore now to supply 

 the following more detailed and accurate information and to base 

 it upon the hi7id claws. The claws more particularly referred to 

 in the tabulation in Part I. were those of the front legs, — but as
